'Applicationrfiled July 6, 1916. Serial No. 107,819.

To all whom it may concern:

Be it known that I, RICHARD W. LLOYD, a citizen of the United States, residing at Verndale, in the county of Wadena and State of Minnesota, have invented certain new and useful Improvements in Liquid- Dispensing Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in liquid dispensers and more particularly to operating mechanisms, for the pumps or other control units thereof.

The object of the invention is to provide a simple and inexpensive arrangement of parts for accurately vending different quan tities of liquid upon the insertion" of a coin,

the device being primarily designed for dispensing gasolene and being operable from coins of different values, liquid discharged being controlled by the value of the coin.

With the foregoing general object in view,

the invention. resides in certain novel featuresof construction and in unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which Figure 1 is afront elevation of the improved liquid dispensing device;

Fig. 2 is a sectional view thereof on the plane of the'line 2-2 of Fig. 1 with all parts in normal position;

Fig. 3 is an enlarged sectional view simi-.

lar to Fig. 2, showing the manher in which the machine is set in pperation by the insertion of a quarter of a dollar;

Figs. 4 and 5 are transverse sections on the planes of the lines Fig. 3;

' Figs. 6, 7 and 8 are showing different positionsof parts to be described.

Tn specifically describing the structure shown in the drawings above briefly described, similar characters will be employed to designate corresponding partsthroughout. the several views and reference will be herein made to the numerous elements by their respective indicesi To this end the num ral 1. desi n tes ahollow sta dard. ris

the quantity ofv H and 5-5 of.-

detail sectional views ing from a pump cylinder 2 but not in communication .the lower end of the standard being adapted to be embedded in the ground as is also a supply tank (not shown), which tank supplies the liquid to the cylinder 2 through the pipe3. A checkvalve 4: is disposed at the lower end of the cylinder 2 to prevent the return of liquid therefrom into the pipe 23, and a piston 5 is mounted in said cyliner, designated at 6, this valve being adapted to open and the other to close when the piston is forced downwardly to its normal position, whereupon liquid will be contained in the cylinder-1 above said piston to be discharged when the latter is raised, a suitable discharge pipe 7 beingprovided. The pipe 7 leads from the upper end of cylinder 2 to .a suitable point above the ground and is equipped with any suitable type of discharge neck' 8.

The features. of construction so far described are merely shown for illustrative purposes and it is to be understood that the gist of the present invention now to be described is applicable equally as well to other types of liquid dispensers.

An operating mem vertical rack bar 9 at 10 to the upper end 's adjustably secured of the piston rod 11 which risesfr'om the piston 6, the teeth of driven by an bracket 16, cooperating with a contact 17.

said bar being in mesh electric motor 13 when the circuit of said motor is completed. A laterally swinging -knife switch 14 is disposed approximately parallel to the bar 9 and for illustrative purposes is shown as pivoted at its upper end at the point 15 to a suitable wire 18 extends to one terminal of the motor 13 while leading from the other terminal thereof and electrically connected in any preferred manner with the knife switch '14:, is an additional wire 19. The other lead wire 20 is connected with the contact 17. It will thus be evident that when the switch 14 is closed or mother words moved from the position shown in Fig. 2 to that des1gnated 'in Fig.' 3, the circuit; will be completed with the result that the motor 13 will be driven to raise bar 9. This raises piston 6 through the instrumentality of rod, 11 and. dispenses a quantity of liq ld which Patented June 191W.

therewith, said cylinder and said pistonalso having a checkvalve her in the form .of a i with a pinion 12 I is controlled by the distance which bar 9 is permitted to move upwardly, said bar having a number of ranges ofmovement and being limited to any one of said ranges by a plurality of stops to be described.

Slidably mounted in suitable bores 21 which open through the edges of rack bar 9, is a plurality of horizontal stop pins 22 which will be limited in their movement by suitable stops 23 as shown most clearly in Fig. 3. When the bar-9 stands in its nor: mal lowered position, to which position it is always returned by a coiled spring 24, the pins "22 will stand opposite arms 25 which project laterally fromthe knife switch 14. Disposed opposite the pins 22 when in their normal positions, are studs 26 which are mounted on one end of plungers 27, said plungers being slidably mounted in suitable casings 28, each of which is provided with a coin chute 29 adapted to direct coins of different values into spaces 30 between the inner ends of the plungers 27 and operating slides 31 (see more particularly Fig. 3). The slides 31 are normally projected slightly across the lower ends of the chutes .29 by means of coiled springs 32 whereby to check the downward movement of any coin a sufficient length of time to permit permanent magnets 33 to act on said coin if it be of 'magnetizable metal. When, however, any slide 31 is retracted manually by means of its respective knob 31' the coin, if not counterfeit, will drop into the space 30, whereupon the slide 31 may be shifted in the opposite direction with the result that its respective plunger 27 will be projected through the instrumentality of the coin until the latter reaches the discharge chute 34; one of these chutes being provided for each casing 28 as shown. Coiled springs 35 are provided for returning the plungers 27 to their normal positions.

When any stud 26 is projected by its respective plunger 27 it will in turn project the adjacent stop pin 22, the latter now forcing against one of the arms 25 to throw the knife switch 14 into engagement with the contact 17. The result is that the motor 13 is set in operation and raises .bar 9 to discharge liquid through the pipe 7 and nozzle 3. The end of the pin which has been projected is adapted to strike a switch cut-out member when the bar 9 moves upwardly a predetermined amount, whereupon the motor will be brought to a standstill and said bar will be returned to its normal position. During this latter movement, the projected pin will also be returned to its retracted position, all of this taking place due to the arrangement of the novel features of construction explained below.

For illustrative purposes the switch outout member is shown in the form of an arm 36 projecting rigidly from the pivoted upper end ofthe knife switch 147. said arm being disposed in the upward path of the pins 22 when projected. It will thus be clear that as any one of said pins is brought into contact with arm 36, the latter will be forced upwardly to a sufiicient extent to throw the I switch 14 horizontally and thus disengage .1t from the contact 17. Ifthe pin be prothrough the chutes 29 thereof, the bar 9 will move a correspondingly greater distance with the result that more fluid will be discharged from the device.

A normally lowered upwardly moving cam 37 is pivoted within a recess formed in the bracket 16 in such a manner as to permit it to swing upwardly, but to limit its downward movement to a substantially horizontal position. The outer ends of. the pins 22 and the cam 37 are beveled in the same direction as shown respectively at 22 and 37. The cam 37 is disposed beneath the arm 36 so that the'active pin 22 will first contact with said cam and tilt it upwardly until it is cleared by said pin. The moment this takes now moves bar'9 downwardly to its normal position. As this movement takes place the bevels 22 and 37' come in contact with the result that the pin 22 which has been proj ected will be returned to its normal position I to be again forced outwardly when its respective stud 26 is actuated.

A suitable casing 39 will be disposed over all working parts and will be supported by the standard 1 if the latter be employed, and within said casing is a coin box 40 in which the coins from the chutes 34 are received, an appropriate door 41 being provided for the purpose of removing the cash when desired.

By constructing the improved vending machine in the manner shown and described it will be highly efficient and durable and will need no operator. As above stated the devices are well adapted for vending gasolene and they may well be placed at intervals along highways, but they may also be used to advantage in 'garages and the like.
